Boeing Model 767-200, -300, and -400ER Series Airplanes
This AD applies to the airplanes identified in paragraphs (c)(1), (c)(2), and (c)(3) of this AD, certificated in any category.
(1) Boeing Model 767-200 and -300 series airplanes, as identified in Boeing Service Bulletin 767-24-0152, dated September 29, 2006; Boeing Service Bulletin 767-24-0153, dated September 29, 2006; and Boeing Service Bulletin 767-24-0154, dated September 26, 2002.
(2) Boeing Model 767-300 series airplanes, as identified in Boeing Service Bulletin 767-24-0148, dated September 14, 2006; Boeing Service Bulletin 767-24-0149, dated September 14, 2006; Boeing Service Bulletin 767-24-0150, dated September 21, 2006; and Boeing Service Bulletin 767-24-0151, dated September 14, 2006.
(3) Boeing Model 767-400ER series airplanes, as identified in Boeing Service Bulletin 767-24-0147, dated February 20, 2003.
We are adopting a new airworthiness directive (AD) for certain Boeing Model 767-200, -300, and -400ER series airplanes. This AD requires installing new relay(s), circuit breakers as applicable, and wiring to allow the flightcrew to turn off electrical power to the in- flight entertainment (IFE) systems and certain circuit breakers through a utility bus switch, and doing other specified actions. This AD results from an IFE systems review. We are issuing this AD to ensure that the flightcrew is able to turn off electrical power to IFE systems and other non-essential electrical systems through a switch in the flight compartment. The flightcrew's inability to turn off power to IFE systems and other non-essential electrical systems during a non-normal or emergency situation could result in the inability to control smoke or fumes in the airplane flight deck or cabin.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
For the airplanes identified in paragraph (c)(1) of this AD: Within 60 months after the effective date of this AD, install new relays and wiring to allow the flightcrew to turn off electrical power to the IFE system and certain circuit breakers through the right utility bus switch and do all other specified actions, by accomplishing all of the applicable actions specified in the Accomplishment Instructions of Boeing Service Bulletin 767-24-0152, dated September 29, 2006; Boeing Service Bulletin 767-24-0153, dated September 29, 2006; and Boeing Service Bulletin 767-24-0154, dated September 26, 2002; as applicable. The other specified actions must be done before further flight after installing the new relays and wiring.
For the airplanes identified in paragraph (c)(2) of this AD: Within 60 months after the effective date of this AD, install new relay(s), circuit breakers as applicable, and wiring to allow the flightcrew to turn off electrical power to the IFE system and the IFE video and audio circuit breakers through the right utility bus switch and do all other specified actions as applicable, by accomplishing all of the applicable actions specified in the Accomplishment Instructions of Boeing Service Bulletin 767-24-0148, dated September 14, 2006; Boeing Service Bulletin 767-24-0149, dated September 14, 2006; Boeing Service Bulletin 767-24-0150, dated September 21, 2006; and Boeing Service Bulletin 767-24-0151, dated September 14, 2006; as applicable. The other specified actions must be done before further flight after installing the new relay(s) and wiring.
For the airplanes identified in paragraph (c)(3) of this AD: Within 60 months after the effective date of this AD, install a new relay and wiring to allow the flightcrew to turn off electrical power to some of the IFE systems and certain circuit breakers through the left utility bus switch and do all other specified actions, by accomplishing all of the actions specified in the Accomplishment Instructions of Boeing Service Bulletin 767-24-0147, dated February 20, 2003. The other specified actions must be done before further flight after installing the new relay and wiring.
